9DBV0931AKILF

Clock Buffers, Drivers Overview

The Renesas 9DBV0931AKILF is a nine-output fanout clock buffer designed for PCIe applications. It operates with a 1.7V to 1.9V supply voltage and supports frequencies up to 200 MHz. The device accepts an HCSL differential input and provides nine HCSL differential outputs. It features integrated 100Ω terminations for direct connection to transmission lines, eliminating external resistors. The component is housed in a 48-VFQFPN package and functions within an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Nine differential HCSL outputs with integrated 100Ω termination resistors
• Supports PCIe Gen 1 through Gen 5 compliance standards
• Accepts spread spectrum input signals for EMI reduction
• Includes output enable pins for individual clock management

Clock Buffers, Drivers Applications

• PCIe Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'KILF' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm moisture sensitivity level (MSL) ratings prior to surface mount assembly. Ensure the 48-VFQFPN exposed pad footprint matches the target PCB layout specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a single HCSL source must drive nine downstream PCIe loads. The integrated 100Ω termination simplifies board design by removing discrete resistors. Verify that the 1.7V to 1.9V supply rail aligns with the system power architecture. Consider the 200 MHz maximum frequency limit for high-speed data link requirements.

Clock Buffers, Drivers Part Context

This part belongs to the 9DBV09x1 family of 1.8V PCIe fanout clock buffers from Renesas. It shares architectural similarities with the 9DBV0541 and 9DBV0741 models but provides nine outputs instead of five or seven. The device is engineered to reduce board space and component count compared to standard HCSL solutions requiring external termination.

Clock Buffers, Drivers Replacement Considerations

The 9DBV0941AKILF serves as a functional equivalent within the same product family. Both parts offer nine outputs and similar electrical characteristics. Verify pin compatibility and specific thermal performance metrics before substituting.
